TUBING RELEASE VALVE.

Application filed. May 5,

This invention is an outlet valve construction for pump tubing, flow pipes, and the like.

An object is to make a construction to be incorporated into a pump tubing above the pump mechanism so that when it is desired to pull the pump tubing and pump, the valve may be opened to allow the contents of the pump tubing to run downwardly and out.

Other objects and advantages will appear from the drawings and specification.

The drawings illustrate an outlet valve construction for pump tubing embodying the principles of our invention.

Figure 1 is a side elevation looking in the direction indicated by the arrow 1 in 2, the pump tubing being broken away above and below the outlet valve construction.

Fig. 2 is a vertical diametrical sectional detail on the lines 2-2 of Figs. 1, 3 and 5, including thewell casing, and parts being omitted in Figs. 3 and 5. V

Fig. 3 is a horizontal section on the line 33 of Fig. 2' and showing the valve closed.

Fig. 4 is a view analogous to Fig. 3 and showing the valve open.

Fig. 5 is a horizontal section on the line 5-5 of Fig. 2.

The details of the outlet valve construe tion for pump tubing shown in the drawings are as follows: i

The section of pump tubing 1 is preferably located above the pumpcylinder and plunger mechanism and may be any ofthe usual sizes. A valve casing 2 is clamped upon the pump tubing 1 and is formed in two pieces 3 and 4 meeting upon the longitudinal diametrical lines 5 andclamped together bybolts 6 and fitting rotatably upon the pump tubing 1. An annular chamber 7 is formed horizontally in the casing 2 around the tubing 1,.the vertical wall 8 of the chamber being eccentric to the tubing 1 and there being outlets 9 through the wall'S." A valve seatmember 10 is tapped through onewall of; thetubing 1 and has a valve seat 11 upon its inner end. The outer end of the member 10 is closed by a flange 12 and 0penin'gs'13 are formed laterally inside of the valve 12. A valve head 14 fits the seat 11 and has a stem 15 extending through the flange 12. A springseat 16 is fixed upon the outer 'end of the stem 15 and an expansive coil spring 1924. Serial No. 711,182.

17 is mounted upon the stem 15 between the seat16 and the fiange 12, the tension of the sprlng being exerted to hold the valve 14 closed.

lVhen the pump tubing 1 is turned so that the. valve stem 15 is at the greatest width of the chamber 7 between the wall 3 and the tubing 1, as in. Fig. 3, the stem 15 is short as required to allow the valve head 14 to seat, and when the pump tubing 1 is rotated 1n the casing 2, the outer end of the valve stem 15 bearsv against the inner face of the wall 8 and forces the valve 14 away from the seat 11 as shown in Fig. 4.

An annular chamber 13 is formed in the casin g 2 around the tubing 1 and a pin 19 is fixed through the tubing 1 and extends in to the chamber 18 to hold the casing 2 from moving longitudiiially upon the tubing 1. Stops 20 and 21 are formed in the chamber 18 to limit the rotation of the tubing 1 in the casing 2 to halt a turn back and forth, as shown in Fig. 5.

Sockets 22 and 23 are formed at one side of the casing 2 and similar sockets 24, and 25 are formed at the other side. The bowed leaf spring 26 is mounted with its ends in thesockots 22 and 23 and the ends of the spring are bent to form hooks 27 and 28, and pins 29 and 30 are mounted through the walls'of the sockets and loosely through the hooks to. hold the spring in place and allow the ends to slide. A guide pin 31 is fixed through the center of the spring and an expanslon coil spring 32 is mounted upon the pin 31 and against tne casing 2, the tension of the spring 32 being exerted to force the center of the spring 26 outwardly. In a like manner, the bowed leaf spring 33 fits in the sockets 24 and 25 and has hooks 34 and 35, and pins 36 and 37 are inserted through the side walls of the sockets and through the hooks to hold the spring in place, and a pin 33 extends inwardly from the center of the spring 33, and an expansion con spring 39 is mounted upon'the pin 38 against the side of the casing 2. V

Knobs 40'and 41 extend from the casing 2 into the inner ends of the springs and 39.

When the outlet valve construction has contracted and placed under tension and form runners to slide down the casing Q, and when the pump tubing 1 has been set the tensions of the springs 26 and 33 and 32 and 39 will be suli'icient to hold the valve casing 2 from rotating in the well casing 42 so that by manipulating the upper end of the pump tubing 1, the tubing may be turned to bring the pin 19 into engagement with the stop 21 and the valve 1% is closed so that the pump may operate to raise liquid upwardly through the tubing 1 and when the pump mechanism becomes clogged or worn and it is desired to raise the pump tubing 1, the upper end of the pump tubing 1 may be manipulated to turn the pin 19 backwardly to engage the stop 20, and the valve lt will be opened to allow the contents of the pump tubing 1 to run out through the ports 9 as the pump tubing is raised, thereby avoiding the necessity of lifting the load within the pump tubing and avoiding the nuisance due to handling the pump tubing loaded with oil and the like, as the sections of tubing are disconnected at the upper end.

The outlet valve construction may be advantageously used near the lower ends cl flow pipes so that when the well becomes sanded and the lower end of the flow pipe clogged and it is desired to remove the flow pipe, the contents of the flow pipe may be discharged through the outlet valve con struction.

Heretofore, when it became necessary to pull a pump tubing, it has been usual to raise the pump tubing a hundred feet or more up into the derrick and unscrew it at the casing head and the oil in the hundred feet of tubing runs out at the point of disconnection and runs all over the derrick floor and wastes the oil and every once in a while catches lire and burns the rig up.

Various changes may be made without departing from the spirit of our invention as claimed.
